Synology has been producing community connected storage (NAS) know-how for over 20 years, and its gadgets have maintained a constant look and really feel. In that point, the firm has developed a extremely polished working system that’s packed with a vast number of bespoke and third-party apps that do the whole lot from merely backing up information on a house or workplace community, by way of managing a family’s multimedia necessities, to working a enterprise’s total IT stack. The latter contains enterprise-grade backup, all types of server performance, electronic mail and web-hosting, digital machine administration, surveillance digicam administration and a lot, way more.
In more moderen years, Synology has hunkered down in its personal section of the NAS market – eschewing broad compatibility with third-party {hardware} suppliers and a Wild-West software neighborhood in favor of a extra closed and skilled working surroundings, the place you must purchase costly Synology drives to populate the bins. Whereas these compatibility modifications have pushed some customers away, what stays remains to be an extremely sturdy, well-supported and well-documented ecosystem that has a large neighborhood following.
The brand new DiskStation DS925+ is one thing of a standard, sweet-spot measurement that may swimsuit new customers and community admins alike. At a look, it seems to be precisely like a number of generations of its predecessors and it operates very very similar to them. Its most important options embrace 4 bays that help each 3.5-inch and 2.5-inch drives and two M.2 NVMe SSD slots. Its tool-less design and easy setup wizards make it fast and simple to construct, and you may be up and working in lower than quarter-hour. It runs quietly and may be positioned on high of a desk or hidden away (in a ventilated location) discreetly. To informal customers (with deep pockets) who need entry to Synology’s apps and want solely primary NAS performance, we may cease there. Fans will need to know extra.
The listing of appropriate drives is now smaller than ever. Whereas Synology has kicked certification of third-party drives over to distributors like Seagate and WD, it doesn’t seem to have resulted in additional selection… but. At the time of writing, you’re nonetheless restricted to Synology’s newest Plus Collection client drives (which go as much as 16TB), its Enterprise drives (as much as 20TB), its 2.5-inch SSDs (as much as 7TB) and its Enterprise-level M.2 NVMe drives (as much as 800GB). All of them are significantly dearer than incompatible third-party counterparts.
The DS925+ comes with considered one of its two SO-DIMM slots populated with 4GB of DDR4 ECC RAM. You possibly can improve to 2 sticks of Synology’s personal 16GB ECC RAM (for 32GB complete) if required, however not in case you’re trying to save cash. The introduction of error-correcting (ECC) RAM at this degree is a boon, nonetheless.
It must be famous that in case you’re trying to the DS925+ as an improve for an older Synology NAS, it will permit third-party drives if it acknowledges an current DSM set up. Nevertheless, you’ll get fixed drive compatibility warnings in return.
Optimistic new {hardware} options embrace a beefed-up, quad-core, eight-thread AMD Ryzen V1500B processor (notice that there’s no built-in GPU) and its two community ports are lastly 2.5GbE. There are each entrance and rear-mounted USB-A 3.2 Gen 1 ports plus a new, barely controversial, USB-C port for connecting an exterior, 5-bay extension unit (changing outdated eSATA-connected choices). What’s most bothersome, although, is the lack of a PCIe community enlargement for upgrading to 10GbE connectivity, which limits the attainable community switch speeds.
Finally, the preliminary outlay for a DS925+ may be huge in comparison with rivals on the market. Nevertheless, in case you’re going to utilize the huge libraries of free software program purposes and licenses, it’ll characterize nice worth.
Synology DiskStation DS925+: Worth & availability
Synology’s DiskStation DS925+ solely not too long ago launched and has restricted availability in solely a few markets. It’s listed at $830 / £551 / AU$1,099.
General, it’s properly priced in comparison with its closest rivals reminiscent of the TerraMaster F4-424 Max, in addition to different Synology NAS gadgets.
Synology DiskStation DS925+: Design & construct
Whereas the DiskStation DS925+ seems to be like its predecessors, I felt that it was considerably extra sturdy and much less rattly than a few of its forebears. No matter that, it’s nonetheless a small and discreet black box that won’t draw consideration to itself, wherever it’s situated.
The tool-less design makes including onerous drives easy. For 3.5-inch drives, you simply elevate up the drive bay door, pull out the drive tray, unclip the tray’s aspect bars, put the drive in the tray, clip the bars again on (they use rubber grommets to cut back sound and vibrations) and slide it again in. In order for you, you possibly can ‘lock’ every drive bay with a key to discourage opportunistic thieves.
Including RAM includes eradicating the drive bays and including SO-DIMMs to the inner slots on the aspect. Including the M.2 NVMe drives includes merely unclipping the covers on the base and sliding them in. Including six drives takes lower than 5 minutes.
A totally populated DS925+ runs very quietly – Synology says simply 20dB – and I can attest that there’s solely a very quiet whooshing noise made by the twin 92mm followers, and the drives solely make occasional, very low clicking and popping sounds.
Putting in the working system can be easy. A QR code in the box supplies entry to a web-based setup doc with a hyperlink that robotically finds your NAS on the community earlier than providing to put in the whole lot for you. After a fast firmware replace, it reboots and you’ll be trying at the DSM desktop, in a internet browser, simply a jiffy later. The NAS will then immediate you to signal into a Synology account, arrange SSO and MFA log-ins and set up some primary apps.
Newcomers may wrestle at first with the terminology surrounding the preliminary setup of the drives, however (at the primary degree) the NAS walks you thru the course of. It includes organizing the drives into a storage pool, then creating a quantity and then including folders. You’ll even be prompted to listing which customers can have View, Learn or Write entry. At this level you’ve bought practical network-attached storage that may be accessed throughout your community.

The working system is well-polished and putting in bespoke and third-party apps is straightforward because of the Package deal Heart software which operates like a free App Retailer. It’s additionally easy to allow distant entry utilizing Synology’s QuickConnect ID short-web-link system.
An fascinating change with the DiskStation DS925+ is the elimination of the (6Gbps) eSATA port for connecting Synology’s elective, legacy, exterior drive bays and its alternative with a single (5Gbps) USB-C port which connects to a Synology DX525 5-bay enlargement unit. I did not have an enlargement bay readily available to check this, however the efficiency distinction must be minimal.
Whereas there are solely two 2.5GbE community ports, you possibly can mix them in numerous methods, with the best (load balancing) changing into operational in simply a few clicks. It’s extra suited to a number of connections slightly than bettering high pace, although.
Lastly, it’s price noting that compatibility with third-party drives is now strictly restricted. At the time of writing, the DS925+ was solely appropriate with its personal (as much as 16TB) prosumer Plus Collection onerous drives, its (as much as 20TB) Enterprise Collection onerous drives and (as much as 7TB) SSDs, plus its 400GB and 800GB M.2 NVMe drives. All of those price significantly greater than third-party equivalents. Synology is blunt about why it has restricted compatibility a lot – it bought sick of dealing with help requests that usually boiled all the way down to conflicts and crashes brought on by drive failures and subsequent arguments with third-party drive distributors. Whereas it’s annoying, I can sympathize with that.

Synology DiskStation DS925+: Options
It’s tough to know simply the place to begin with the quite a few options which might be obtainable with the DiskStation DS925+. It performs nearly each enterprise and client process you possibly can think about. For a lot of smart-home customers, the numerous multi-device backup utilities, multimedia group instruments and media-server performance (together with Plex, Emby and Jellyfin) shall be used greater than the rest.
For prosumer and enterprise customers, it may be your full-stack IT service supplier. There are apps that may rework your NAS into an enterprise-grade backup answer with off-site (third-party and Synology C2) cloud capabilities; electronic mail server; internet server; Synology Workplace software supplier; surveillance digicam supervisor; anti-malware safety; digital machine supervisor and a VPN server.
In all of those purposes, a number of consumer licenses are included, which boosts the worth proposition by way of the roof.
There’s a multitude of third-party purposes and high-quality documentation (masking nearly the whole lot) that has been created by a giant and mature Synology-enthusiast neighborhood.
Community admins may also like the quite a few drive-formatting choices, granular consumer permission administration and SSO and MFA safety choices.
Storage capability may be elevated by way of a USB-C related, five-drive-bay enlargement unit.
The 2 USB-A ports (entrance and rear) have had many capabilities eliminated to allow them to no longer be used to attach potential safety nightmares like printers, media gadgets, or community adapters, however they’ll nonetheless be used for connecting exterior USB storage gadgets.
The dual 92mm followers are quiet and, in conjunction with well-designed vents, do a good job of cooling the NAS. That mentioned, be sure you place it in a location the place airflow isn’t impeded and the vents gained’t get clogged with mud.
Synology DiskStation DS925+: Efficiency
To check the DiskStation DS925+, I put in 4 Synology 3.5-inch, 4TB onerous drives and formatted them with Synology’s personal RAID-5-like Btrfs file system which gives striped efficiency boosts, disk-failure redundancy safety and quite a few enhancements that work with Synology’s backup utilities. It left me with a 10.4TB quantity and meant I may lose/take away anybody drive with out struggling information loss.
I additionally put in two 400GB M.2 NVMe SSDs as a single Btrfs storage quantity (they can be used for caching) which gave me a usable capability of 362.4GB.
I transferred information from one quantity to the different and hit sustained switch speeds that peaked at 435MB/s, however most individuals shall be transferring information externally.
I subsequently carried out a number of assessments to seek out its real-world limits, see what doing with out a 10GbE port possibility meant and uncover what advantages the two (configurable) 2.5GbE LAN ports supplied. I did this by connecting the NAS to a high-end, TP-Hyperlink Deco BE85 Wi-Fi 7 Router (with 10GbE LAN ports) by way of Ethernet and downloading giant video information utilizing numerous wired and wi-fi configurations.
I in contrast the DS925+’s efficiency to that of an older, two-bay Synology DiskStation DS723+ that has a 10GbE wired connection, a twin 3.5-inch onerous drive quantity and a newly fitted, single, 800GB Synology M.2 NVMe SSD-based quantity.
I examined utilizing a high-end Asus ROG Strix Scar 17 X3D gaming laptop computer with a 2.5GbE LAN connection and Wi-Fi 6E, in addition to a new Core Extremely (Collection 2) Asus Vivobook 14 Flip with Wi-Fi 7.
I began with the DS723+ which I’ve been utilizing for testing Wi-Fi routers. With the Scar’s 2.5GbE Ethernet port related by wire to the Deco router, I noticed sustained switch speeds that hit 245MB/s for each the DS723+’s HDD quantity and its NVMe quantity. Over a 5GHz Wi-Fi 6E wi-fi connection, this dropped to 194MB/s for each volumes. Over a 6GHz Wi-Fi 6E wi-fi connection, it achieved 197MB/s utilizing the HDD quantity and 215MB/s for the NVMe quantity.
Switching to the Wi-Fi 7 VivoBook, on the 5GHz wi-fi connection, it managed 180MB/s for each the HDD and NVMe volumes. Nevertheless, when utilizing the 6GHz Wi-Fi 7 community, it achieved 244MB/s for the HDD quantity and an astonishing 347MB/s for the NVMe quantity. That proper there may be the energy of getting a 10GbE-equipped NAS (with an NVMe drive) related to a Wi-Fi 7 community. Cables, schmables! That’s greater than sufficient for modifying a number of streams of UHD video at as soon as.
So, how did the newer DS925+ examine? When it was related to the Deco by way of a single 2.5GbE port, the 2.5GbE LAN related Asus laptop computer reached 280MB/s for the HDD quantity and 282MB/s for the NVMe quantity – a good 35MB/s faster than the two-bay DS723+. Over 5GHz Wi-Fi these scores each dropped to 190MB/s which is analogous to the DS723+, illustrating a doubtless 5GHz Wi-Fi bottleneck. Apparently, efficiency was persistently slower throughout the Scar’s 6GHz assessments, the place it hit 163MB/s (HDD quantity) and 172MB/s (NVMe quantity), however that is once more doubtless brought on by the community, not the NAS.
When the VivoBook related by way of the 5GHz community, it managed 186MB/s transfers for each volumes. Over Wi-Fi 7 this jumped as much as 272MB/s for the HDD quantity and 278MB/s for the SSD quantity. So, to this point, the file switch efficiency advantages of getting NVMe storage on the DS925+ aren’t vital when passing by way of the bottleneck of its 2.5GbE LAN port.
Consequently, I bonded the two 2.5GbE connections collectively to type a ‘single’ 5GbE connection in an effort to spice up efficiency. This takes simply a few clicks in DSM’s management panel. I opted for the primary Adaptive Load Balancing possibility, however there are a number of different configurations for numerous kinds of community topology.
So, with the DS925+’s two Ethernet cables forming a single 5Gbps connection to the Deco router, I ran the assessments once more. The two.5GbE-connected ROG Strix Scar noticed switch speeds (to each the HDD and SSD volumes) solely attain 168MB/s, which is round 120MB/s slower than when the NAS was related by way of a single 2.5GbE wired connection. Over 5GHz Wi-Fi this boosted (barely) to 188MB/s for each volumes and over the 6GHz community, it dropped again to 170MB/s for each volumes. It’s honest to say that combining the DS925+’s two 2.5GbE ports is healthier suited to dealing with a number of community streams slightly than boosting efficiency of a single connection.
Nonetheless, I repeated the check with the VivoBook. Over 5GHz Wi-Fi, each volumes noticed switch speeds of 176MB/s. Over 6GHz Wi-Fi 7, it hit 283MB/s.
So, what have we realized about the DS925+’s file transfer-speed potential? Utilizing a 2.5GbE wired connection to and from the router, it tops out at 280MB/s. Connecting the laptop computer by way of 5GHz Wi-Fi sometimes sees switch speeds of between 160MB/s and 185MB/s, however over 6GHz Wi-Fi 7, as much as 283MB/s is feasible. Which means, in the proper circumstances, Wi-Fi 7 can match 2.5GbE connection speeds.
We additionally realized that combining the DS925+’s two 2.5GbE connections (at least, in my explicit setup) reduces the high switch pace. Most significantly, which means dropping the possibility for a 10GbE improve stops us hitting insane 347MB/s speeds over Wi-Fi 7, and 283MB/s is the diminished ceiling. As such, it’s straight-up not price utilizing the M.2 drives for file switch efficiency boosting as the 2.5GbE connection(s) act as a bottleneck.
That every one mentioned, the M.2 drives can nonetheless enhance efficiency by way of caching performance and Synology notes it may give a 15x enchancment to random learn and write IOPS. This shall be a a lot greater deal in conditions with a number of connections occurring concurrently.
Whereas some high-end customers will miss the choice to improve to a 10GbE efficiency ceiling, I discovered it’s nonetheless greater than sufficient to facilitate very excessive bitrate, 60FPS, UHD+ video playback (and a number of UHD video stream modifying) along with having a number of simultaneous connections performing quite a few lesser duties.
- Efficiency rating: 4.5 / 5
Do you have to purchase the Synology DiskStation DS925+?
It has turn out to be regular to gripe about the design selections and limitations that Synology imposes on every era of its prosumer NAS bins. Nevertheless, if we eradicate the potential purchasers it gained’t swimsuit – i.e. those that want a 10GbE connection and those that can’t afford all the costly Synology onerous drives required to populate it – it’s completely price shopping for.
Its extremely developed chassis is deceptively properly constructed when it comes to tool-less entry, rigidity, cooling and airflow.
